MW2: Configs Update 2
Written by jockyitch

MW2 appears difficult to tweak.

Spaced Farout in Germany reports that the console DOES NOT work. Clearly certain cVars have been blocked, for example the lean command will not work if added to the configuration.

Here are the single player and multiplayer configs for MW2, courtesy of Spaced Farout:




Update 1  Multiplayer specific notes

Console commands

The console does not work like it used to. Some cVars can be changed but you have to manually change them in the config file.

Note that some changes to the config will just result in the file being wiped. The game just deletes it and then recreates it on restart.

An error message stating that there is a problem loading the configuration file is common. Obviously, having a back-up configuration is a must if you try tweaking this file.

Apparently, game volume, fps and mouse sensitivity changes can be made without the over-write issue.


Another reader, who was using a Core 2 Duo running at stock 3.0 Ghz with 8 GB of RAM and a GTX 260 standard edition (without all the stream processors active) Windows Vista Ultimate x64 with all current updates and the latest beta drivers for the graphics card, was getting 50fps with default settings during the training mission, 100fps looking down range. Anti-aliasing was set off due to the demanding visuals in-game.

Those are (barely) good numbers for a pub, but certainly they are poor for any competitive gaming.

You are able to change the maxFPS cap by editing the config file itself. Note that changing that variable through the console is not currently possible.

Default setting is seta com_maxfps "85".


Currently this is set at 65 and appears hard wired.


Max packets is set low by default, \seta cl_maxpackets "30" and snaps are set to "20". If this game could have actually been played on a proper dedicated server, this setting would have generate somewhat poor registration. Of course, the game is listen-server-based and the poor registration  that was expected is currently being reported. This is unsurprising given the higher potential for poor quality connections now possible.


Apparently, Alt+Tab works in the singleplayer mode but not in multiplayer. Get yourself fragged in S&D and you will simply have to find another way to entertain yourself until the game is over.

Differences in the CoD4 and MW2 config CVARS

New commands for MW2 are noted below (there are quite a few cvars missing from CoD4 and are apparently now hard-wired, so to speak).

Note the splatter, shatter and water commands which indicate some visualization improvements over the CoD4 engine.
